Most of the time, I sew the binding onto the front, then turn it to the back and stitch in the ditch from the front.
But I don't trim the quilt perfectly until the binding is sewn on. That way I can see to save my points when needed. After the binding is sewn on, then I trim the back and batt at exactly 3/8 of an inch from the sewing line. I use a 12 inch ruler and rotary cutter to make short cuts at the correct distance. (Watch out for the corners. Don't cut that fold in the binding as you turned the corner.) With a little extra batt there, you can get a full binding. I only pin it at the corners.
This method works well for straight cut binding. I wouldn't try it with bias binding.
